Abstract

The invention discloses a processing method and device for voice recognition in a vehicle, electronic equipment and a storage medium. The method comprises the following steps: reference audio is obtained and recorded, and therefore recorded play-back audio is obtained; pure voice is obtained, noise data satisfying object signal to noise ratio conditions is chosen from the play-back audio, noisy voice is obtained after the noise data is superposed on the pure voice, the noisy voice and the reference audio are input as input data into an AEC module, echo cancellation processing operation is performed on the input data via the AEC module, and training data containing AEC residual noise can be obtained. Thus, in actual online application, voice in the vehicle can be trained and recognized viathe training data containing the residual noise, voice recognition effects are improved, recognition performance and recognition stability are improved, and user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a processing method, device, electronic equipment and computer-readable storage medium for speech recognition in a vehicle environment. Background technique [0002] In the application scenario, echo cancellation interrupts the processing. For example, when waking up the playback device in the car to play music, the wake-up voice needs to be recognized. In the process of recognizing the wake-up voice, due to various noises in the car, it is necessary The wake-up voice performs noise suppression and echo cancellation. However, the echo cancellation in the prior art is often not thorough enough, and there will be some residual noise, and this residual noise will directly affect the recognition effect of the wake-up speech. Contents of the invention [0003] The object of the present invention is to solve one of the above-mentioned technical problems at least t...
